Definitions

  • the present invention relates to a hydraulic machine equipped with a hydraulic pressure generator group used to propel the machine and to supply hydraulic power to hydraulic tools.
  • a hydraulic machine equipped with a hydraulic pressure generator group used to propel the machine and to supply hydraulic power to hydraulic tools.
  • Such a machine is in particular intended for mobile railway maintenance sites.
  • hydraulic tools such as: drills, screwdrivers, screwdrivers, chainsaws, impact wrenches. These hydraulic tools are then connected to a hydraulic pressure generator group which must generally be moved to monitor the site.
  • Known generators are not very suitable for traveling.
  • the present invention relates to a machine equipped with a hydraulic pressure generator group which is self-powered, the group serving both to propel the machine and to supply hydraulic power to the tools.
  • This machine is provided with wheels driven by hydraulic motors which provide a significant torque which allows the easy crossing of obstacles.
  • the machine is provided with a braking system which cooperates with the hydraulic motors so as to control the differences in the rotational speeds between the wheels (in the event of resistance on a wheel for example).
  • the chassis of the machine allows the wheels to follow the movements of the ground although the hydraulic motors are fixedly mounted on this chassis.
  • the machine equipped with a hydraulic pressure generator group, is essentially characterized in that this group is mounted on a wheeled vehicle and that at least two of the wheels of this vehicle are each driven .by a hydraulic motor powered by said pressure generator group.
  • the machine comprises braking members acting independently on the wheels driven by said hydraulic motors.
  • the motors are mounted on the chassis of the vehicle which consists of a half-chassis carried by two wheels and another half-chassis carried by two other wheels, these two half-chassis being coupled together. one to the other by a central articulation allowing the relative rotation of the two half-chassis around a vertical axis and a horizontal axis, hydraulic means controlling the relative orientation of the two half-chassis around the vertical axis .
  • the machine comprises a group generally having hydraulic pressure 1 constituted by pumps 12, 13, 14 driven by a heat engine 11.
  • This group 1 is mounted on a self-propelled vehicle comprising a chassis 2 carried by a train of front wheels 3 and by a train of rear wheels 4. These wheels can be coupled to railway wheels, coaxial, so as to allow rail- road.
  • the chassis consists of a half-chassis 21 carried by the wheels 3 and a half-chassis 22 carried by the wheels 4. These half-chassis are coupled to each other by a central articulation 23.
  • the half-frame 21 which will be called half-engine chassis carries group 1.
  • the wheels 3 of the carrier half-chassis are directly driven by motors 5 which are each coupled to a wheel.
  • the hub of each wheel is fixed on the output shaft of a motor 5 which is fixed to a flange of the half-chassis.
  • the rear wheels 4, non-driving, are mounted by means of bearings on the half-chassis fuses 22.
  • the central articulation 23 is a clevis articulation comprising a lever 231 joined so as to be able to pivot about a vertical axis to a fork 232 secured to the half-frame 21.
  • This lever is joined by 233 with a horizontal axis at the allows articulation cylindrical / semi-chassis 22. This articulation / relative rotation of the two half-chassis around a vertical axis and around a horizontal axis by the axis 233.
  • the end of the lever 231 is coupled to the rod of a steering cylinder 6, the cylinder of which is coupled by an articulation to the half-frame 21.
  • the outputs and re-entries of the rod of this cylinder determine the relative orientation of the two half chassis 21 and 22.
  • Brakes 7 are provided for braking the drive wheels 3 independently of one another. These brakes are of the jaw type, the jaws being maneuvered by hydraulic cylinders 71. By acting on one or the other of the brakes, it is possible to control the differences in rotation of the hydraulic motors.
  • the hydraulic pressure generator group supplies the hydraulic motors 5 and connections 91 to which hydraulic tools can be connected. Furthermore, it supplies hydraulic power to the brake cylinders 71 and for the control of the steering cylinder 6.
  • the pressure generator group 1 consists of a heat engine 11 driving a variable displacement pump 12 and constant displacement pumps 13, 14.
  • the variable displacement pump 12 supplies the hydraulic motors 5 in parallel and d on the other hand of the fittings 91, the supply being controlled by a distributor 98 alternately towards the motors or the fittings.
  • the steering control cylinder 6 is supplied by means of a manually controlled steering device 93 itself supplied by a constant displacement pump 13.
  • This device 93 with manual control is operated by a steering wheel placed on the switchboard of the machine so that it can be maneuvered by the operator.
  • This device 93 is mounted on a slide of the engine half-chassis so as to be able to slide linearly by acting on the flywheel. It is connected to the control lever of the variable displacement pump 12 by a mechanical transmission. In this way, by linearly moving the device 93 by the handwheel, the operator controls the flow rate of the pump 12.
  • Each brake cylinder 71 can be supplied independently by the distributor 94 supplied by a pump 14.
  • the constant displacement pump (s) 13, 14 supply fittings, not shown, to which hydraulic tools working at constant speed can be connected.
  • the vehicle could include a system for changing the wheel spacing.
